the perfect intro song!

i've been training in mma for the past 7 months and finally my trainers asked me if i would be willing to fight in an amateur match they're putting together. i narrowed down my nickname to two possibilities. all i need is an idea on the song i should come out to for my first fight! there's so many i can't narrow it down. what would you come out to? mind you i will never come out to anything but strange music!
